IMPROVEMENT IN CARPET FABRICS.

Specification forming part of Letters Patent No. 205,708, dated July 2, 1878; application tiled January 28, 1878.

To all whom it may concern.

Be it known that I, BENJAMIN WEIAND, of Philadelphia, Pennsylvania, have invented a new and useful Improvement in Carpet Fabrics, of which the following is a specification:

AWT-he object of my invention is to produce a cheap carpet fabric, into the pattern of which a greater number of colors may be introduced than usual; and this object- I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in whichl Figure l is a diagram illustrating my invention; Fig. 2, an exaggerated longitudinal section of the fabric, and Fig. 3 an exaggerated transverse section of the same.

In making my improved carpet fabric I elnploy one set of thick figuring-warps, A., one set of fine binding-warps, c, two sets of thick iiguring-wefts, B and D, and one set of tine binding-weits, b.

The warp-threads A and wefts B and D are combined in the manner shown clearly in Figs. 2 and 3. Thus, in Fig. 2 it will be observed that the warp-thread A appears both upon the face and back ofthe fabric at different points, while at other points it is embedded between the two wefts, which are also changed from one surface to the other.

It will be understood that the relation of the warps A and wefts B and D to each other is governed by the demands of the pattern and the single or double faced character of the carpet which is to be produced.

The figuring weft-threads B and D are bound together by the fine warps a, and the figuringwarps A by the tine wefts b,- and in order to firmly bind the warps A and wefts B and D together, so as to make the fabric strong and durable, the warps a and wefts b arc interlocked, in the manner shown in Figs. 2 and 3.

In the above-described carpet both the warp and wefts appear on the surface, so that a greater di versity of color m ay be introduced into the pattern than where the pattern is formed solely by the warps 0r the wefts, and, owing to the fact that but one set of iiguringwarps is used, the Jacquard machine may be made simpler and lighter than when two sets of such Warps are employed. Moreover, the weft or iilling threads are much less expensive than the warp-threads, and the cost of my improved carpet is thereby considerablyT decreased.

I do not desire to claim, broadly, a carpet fabric in which the pattern is formed by both the warp and weft threads, as such a fabric has been made previous to my invention; but

I claim as my invention- A carpet fabric in which are combined iiguring-warps A, figuring-wefts B and D, ine binding-warps a, and iine binding-wefts b, all substantially as specied.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

BENJAMIN WEIAND.
